When Sauron brought Vivian back to the slums, he bought a loaf of black bread as thick as an arm with 3 copper dollars along the way. It was the hard kind of black bread that could be used as a weapon against thieving idiots, dealing 1-3 damage. The peasants ground the rye without shelling them, their crude skills result in wood chips and other weird things being mixed into the bread.Once cooled they become as hard as clubs, and only after slicing them with a knife and soaking them in water are they barely swallowable.
